JAMES MocU'r'oHEoN COLEMAN, or WESTMOUNT, QUEBEC, cAn'AnA;

REFRIGERATOR-CAR.

Specification of Letters Patent.

Application filed April 30, 1912. Serial No. 694,283.

To all whom; it may concern Be it known thatI, JAMES MCCUTCHEON COLEMAN, a citizen of the United States of America, and a resident of 356 Olivier avenue, in the city of Westmount, .in ,the Province of Quebec, Canada, have invented certainnew and useful Improvements in Refrigerator-Cars; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to improvements in refrigerator cars, as described in the present specification and illustrated in the accom panying drawings that form part of the same. e v

The invention consists essentially in" the novel means employed forlowering the temperature of the air.-

The objects of the invention are to materially increase the chill in the air without adding to the ice box spaces, to economize in the use-of ice and generally to provide an eflicient refrigeratin car at a minimum cost and suitable for venous food products.

In the-drawings, Figure 1 is a vertical view of one 'end portion ofthe car showing a mid longitudinal section. Fig. 2 is a horizontal section of the same part onthe line AB in Fig. 1. Fig. 3 is an interior perspective detail of a portion of the upper part of the ice box. Fig. 4 is'a fragmentary perspective detail of the lower part of the Fig. 5 is a fragmentary elevational view, showing the construction of the means employed for cutting off the upper opening to the cooling compartment from the ice containers looking toward the cooling compartment.

Like numerals of reference indicate corresponding parts in each figure. Referring to the drawings 1 indicates the side walls of the car suitably sheeted on the inner side as customary.

2 are the end walls suitably sheeted on the inner side as customary.

3 are the solid partitions dividing off the ice box portions at each end of the car and terminating before reaching the roof, but continuing as partitions to said roof in the gratings 4.

- 5 is a'wall of corrugated sheet metal having the square corrugations 6 and extending upwardlywithin the ice box portions and" terminating at the up er end even withthe top ofth'e solid partition 3 and at the lower end supported on the .slat .bottom 7, said metal wall and the inner wall of the ice box portion forming an air space for the passage of chilled air from said wall 5 and flowing out under the partitions 3 into the interior of the car. There are preferably two such walls at each end with the passage 6 therebetween.

8 is a drip compartment under each ice box having the outlet 9.

10 are stops intermediate of the height of the corrugated wall, adjacent to each solid portion 3 and toward the upper end of said wall 5 on the outer side thereof. 7 11 is a similarly formed slide to the corrugated wall and resting on said stops 10 in its lower position and in its upperposition reaching to the ceiling of the car and held in its upper position by the hooks 12, or by any other suitable means, and completely modifying the uses of the gratings 4, thus providing dry cold storage during transport for meats and such commodities, while with the slides down moist cold storage is provided for'other commodities.

In the use of this car the ice boxes at each end of the car are filled with ice,'sai'd ice bein supported on the slat bottoms and, as it me ts, the water dripping into the drip boxes immediately therebelow. The metal corrugated walls become very cold, as they are in direct contact with the ice and present the maximum cooling surface for the size of the compartment, so that the chilled metal absorbs heat and distributes cold air into the spaces around and the heavy cold airdescends and passes out at the lower end into the interior of the car, where its tempera-v ture becomes higher in contact with the food stufis and ascendingas customary, gradually the whole air of the car becoming suitable for storage purposes. The closing of the openings afiorded by the gratings materially affects the air in the car and in place of a mois't cold air quite a perceptible dryness is apparent and this is particularly suitable for meats.

The advantages of this invention for re Patented July 29, 1913.

' rugated walls 5 are preferably secured to the side and end walls of the car by the stay bolts 13 secured by the nuts 14.

What I claim is In a refrigerator car, an ice compartment formed therewithin, a plurality of ice holders within said compartment formed of corrugated sheet metal and spaced from the inner walls of said compartment and from one another, said holders on one side there-' of having a wall shortened from the top and registering with a corresponding opening in the wall between the car body interior and said compartment, the latter Wall being open at the lower end also, slides having corresponding corrugations to said holders and 15 slidably attached to the shortened Walls at the upper ends thereof and adapted to close in said holders from the body of the car and direct the warm air from the car interior to the spaces surroundin said holders.

Signed at the city of l lontreal, Province of Quebec, Dominion of Canada, this 16th day of April 1912.
